Try to find the spot where the photographer was standing.
"7 - 9 -29" - is that the date of the photo? 7 September 1929. It was a Saturday.
Here is a bit of fun - the shipping reports for 7/9/1929 says -
Circular Quay: Malabar 5. John Williams 7a.
Woolloomooloo: . Touraine 4, Orama 7.
Walsh Bay: Nestor 8.

The SS ORAMA (Orient Line, 1924) is recognisable at the Woolloomooloo finger wharf. Seen also in 1925 - [https://www.flickr.com/photos/anmm_thecommons/8262503245]

https://www.flickr.com/photos/beachcomberaustralia looks like a possibility I will check some of the other negatives
https://www.flickr.com/photos/statelibraryofnsw Many of the https://www.flickr.com/photos/state-records-nsw/ photos have the date in the corner in a similar form - I think they came from JJC Bradfield's office and official records. eg -

"...The series consists of black and white photographs which were developed from glass negatives and pasted into large albums. One volume is devoted to the southern approach, two to the northern approach and 11 to the main Bridge. Each photograph is captioned and almost all are precisely dated with the caption if the date is not incorporated into the image."
